NBC Entertainment Chairman Bob Greenblatt on Tuesday took a shot at Donald Trump by saying Trump's "Celebrity Apprentice" routinely yielded dismal ratings when the show was on the air.

The New York Post first reported on Greenblatt's comments, which were posted on his private Facebook page.

"The sad state of affairs thanks to a pompous businessman turned reality TV star (whose show consistently ran LAST in its time period, by the way) who thinks speaking his mind is refreshing," Greenblatt wrote on Facebook. "It's actually corrosive and toxic because his 'mind' is so demented; and his effect will unfortunately linger long after he's been told to get off the stage."

Trump hosted "Apprentice" and "Celebrity Apprentice" for 14 seasons on NBC before launching his presidential bid in July 2015. NBC cut ties with the Republican nominee over his controversial remarks about Mexican immigrants.

Earlier in August, Greenblatt said that Trump will never be allowed to return to "Celebrity Apprentice" "as long as I'm here."

"Celebrity Apprentice" will return to the network last year with Arnold Schwarzenegger as the new host.
